SOIL LOSS COMPARISON - SNOWCAP COAL MINE <br />RECLAIMED VERSUS BASELINE (SHADSCALE REFERENCE AREA) CONDITIONS <br />The following calculations are presented to determine if untreated drainage from the reclaimed ponds 6, 10, <br />7, 9, and 13, CBA Sump, #1, CRDA 1 Road, & G Substation areas are contributing suspended solids to <br />the stream flow or runoff outside the permit area in excess of pre -mining levels. <br />The baseline data for comparison are considered to be those conditions that exist in the Shadscale <br />reference area. The condition of the reference area and the reclaimed areas are based on 2016 <br />surveys performed by Cedar Creek and Associates. <br />Disturbed Area, Ponds 6, 7, 9, 10, & 13 <br />CBA Sump #1, CRDA Road #1 & G Substation <br />Total Perennial Cover+Rock+Litter <br />54.3% <br />528% <br />Perennial Cover: <br />Perennial Cover. <br />Grasses, Grasslikes <br />5.0% <br />Forbs <br />1.2% <br />Shrubs <br />24.1% <br />Other - Rock <br />8.5% <br />Litter <br />Other - Rock <br />156% <br />Litter <br />10.4% <br />Total Perennial Cover+Litter <br />45.8% <br />Canopy (Shrubs) 1 <br />24.1% <br />Ground Cover at Surface (43.8-21 7) <br />21.7% <br />Shadscale reference Area <br />Baseline <br />Total Perennial Cover+Rock+Litter <br />528% <br />Perennial Cover. <br />Grasses, Grasslikes <br />10.4% <br />Forbs <br />08% <br />Shrubs <br />0.3% <br />Shrubs, Cacti & Trees <br />6.8% <br />Other - Rock <br />24.1% <br />Litter <br />10.4% <br />Total Perennial Cover+Litter <br />287% <br />Canopy (Shrubs+ Trees) I <br />1 7.1% <br />Ground Cover at Surface (28.7-7 1) <br />1 21.6% <br />SL -9 Tab -9, Page 5 Revised 10/18/2016 <br />
